MACHINE FOR SHARPENING RAZORS.

SPECIFICATION forming part of Letters Patent No. 659,501, dated. October9, 1900.

Application filed June 1,1900.

To aZZ whom it may concern:

Be it known that I, LEWIS D. WHIPPLE, of Groton, in the county of NewLondon and State of Connecticut, have invented a Cutlery-SharpeningMachine, of which the following is a specification.

This invention relates more particularly to mechanism for sharpeningrazors; and its primary object is to provide improved means forproducing a smooth fine edge.

In the accompanying drawings, Figure l is an end elevation of mechanismembodying my invention. Fig. 2 is a sectional view thereof, taken on theline 2 2 of Fig. 1; and Fig. 3 is a sectional view taken on the line 3 3of Fig. 2.

As illustrated by the drawings, the base 1 supports two pairs of struts2 and 2, which support the respective shafts 3and 3, journaled therein.The shafts 3 and 3 have the respective cylindrical sectors 4 and 4'fixed thereto and the respective intermeshing gearwheels 5 andv 5 fixedthereon. The gearwheels 5 and 5 are arranged so that the disks 4 and 4do not come together, but alternate in passing the place common to thepath of each, and they are caused to travel in the directions of thearms by turning to the right the handle 6, which is screwed upon theshaft 5, and hence cannot turn the disks backward. The revolutions ofthe disks 4 and 4, as described, cause their leather-covered or othercharacter of surfaces 7 and 7 to alternate in rubbing the correspondingedges of the blade 8, which is clamped and held in position by the arms9 and 9, the arm 9 being provided with the jaws 10 and 10, connected bythe pivot 11 and controlled by the screw-threaded key 12. The arms 9 and9' are preferably rigidly connected, as by the member 9". They are heldin laterally-adjustable relation to the disks 4 and 4 by means of thehorizontal bars 13 and 13, having slots 14 and 14 therein and the arbors15 and 15 passing therethrough and screwed into the arms. These arborsare screwed up to a tension sufficient to hold the arms in fixedposition normally, but permitting them to be rocked slightly by thealternating impact of the disks Serial No. 18,709. No model.)

4 and 4 with the blade 8. The arms are rendered adjustable vertically bymeans of the slots 16 and 16 in the struts 2 and 2, through which theclamp-screws 17 and 17 pass into the bars 13 and 13.

It will now be seen that when a blade is held in place by the arms, asshown, and the handle is turned to the right the disks will alternatelyrub the opposite faces of the blade, which faces are held in movablerelation to their corresponding rubbing-disks.

Having thus described my invention, 1 claim I 1. In a sharpening device,a pair of revolving cylindrical rubbing-sectors, in combination withmeans for holding a blade in the respective paths thereof, said sectorsalternating in rubbing the faces of said blade, substantially asspecified.

2. In a sharpening device, a pair of journaled shafts, a pair ofcylindrical sectors and a pair of intermeshing gear-wheels, fixed onsaid shafts, said sectors alternating in passing a place common to thepath of both, and rocking arms for holding a blade in the path of eachof said sectors, substantially as specified.

3. In a sharpening device, a pair of revolving cylindrical sectors,rocking arms for holding a blade in the path of each of said sectors,and means for adjusting the position of said rocking arms relative tosaid sectors, substantially as specified.

4. In a sharpening device, a pair of revolving disk sectors, a pair ofintermeshing gearwheels fixed to said sectors, in combination withrocking arms for holding a blade in the path of each of said sectors,said rocking arms being provided with clamping-jaws for holding saidblade, and means for regulating the rocking resistance thereof,substantially as specified.

In testimony whereof I have hereunto set my hand, in the presence of thesubscribing witnesses, this 22d day of May, 1900.

. LEWIS D. WHIPPLE.
